Input Multiple GAT Aggregation Variables

Description

This function opens a dialog window for the user to select which variables in the shapefile should be aggregated and to what minimum and maximum values. The dialog window looks like this.

• Click Next to continue to the next step.

• Click Cancel to end GAT.

• Click Back to return to the previous step.

• Click Help to get further guidance and open the manual.

Usage

inputGATaggregators(
  shp,
  step = 4,
  min1 = "5,000",
  min2 = "none",
  max1 = "none",

  var1 = "",
  var2 = "NONE",
  backopt = TRUE,
  bgcol = "lightskyblue3",
  quitopt = "Quit",
  buttoncol = "cornflowerblue"
)

Arguments

shp	Spatial layer.
step	Integer step in GAT, for help reference.
min1	Minimum value for the first aggregation variable.
min2	Minimum value for the second aggregation variable.
max1	Maximum value for the first aggregation variable.
max2	Maximum value for the second aggregation variable.
